Vintage Clip On Earrings SAC Black Dome Gold Tone Filigree Back Sarah Coventry

Vintage Clip On Earrings Marked SAC Silvery Gray-Black Dome Gold Tone Filigree Back. These are probably Sarah Coventry from the home parties we remember from the 70s & 80s. However, the "SAC" mark is not officially registered to the company, so it is debatable in parts of the vintage jewelry community.
